Love this simple script! I have a test skill that deals an ungodly amount of damage and I wanted to keep it in the final game but was afraid of it making battles too easy, so I was looking for ways to limit its use (the easiest being to make its MP cost very high.) This script is a much better solution! Makes combat more layered as I can lower the test skill's MP cost so the character can still use other skills if they want, and the use of the test skill becomes more nuanced.

This script does give me another idea:

Would it be possible to add a second function to the script for Hyper Beam-style skills? So the character has to recharge on the next turn and be locked out of any moves (perhaps even with a text on top of the battler sprite saying Aluxes needs to recharge!)
